Mowing the lawn with a 5ft brushhog, running 3/4 rpm (no tach) for 3 or so hours. When I tried to reduce RPM with the throttle it wouldn't come down, even pulled kill cable, no dice. When I pulled PTO out of gear it sped up more. Finally had to re-engage PTO, put in 2nd Low and drug the brakes to load the engine and then was able to reduce RPM and then kill the motor.

Strange. I fired it right back up did some more mowing and was able to reduce throttle and kill as normal.

Wasn't running hot, it was in the "Run" zone on the temp gauge but it is a 104 degree day here in sunny Arizona. I've been flushing radiator out as it has lots of crap in it and just changed the oil after the high rpm run today.

This has the early pneumatic CAV Diesel injection pump (Tractor Serial number 1420) 1960.

Any ideas? I'd hate to blow up the motor from over-revving it, cuz I have lots of work for this old gal to do around here.

Hi Bart, fuel rack could be sticking in injection pump. Try some Diesel fuel conditioner or a couple tablespoons of 2 cycle engine oil in the fuel.
You can stall it by putting it in 3rd or 4th high and braking hard.

Air governor stuck. Make sure all linkage is free and the governor is freed up. Its been a long, long time but I think there was a oil line to the air governor.

Likely, the governor diaphragm in the IP has failed.

A little Gasoline in the Diesel will cause this kind of action. If it does take off and nothing will slow it down get clear (run to the rear) so you do not get hit by flying engine parts. You might want to drain the tank and replace it with good clean fuel.

Any Natural gas around? Any gas wells being drilled close by?

No gas around this way in Arizona.

Wondering if this is a problem with the early CAV pneumatic governors.

was it blowing lots of smoke at same time? Governor diaphragm. Easy to replace, just make sure the new one is oiled if leather, and CLEAN!
